3 IEC: INTERNATIONAL ELECTROTECHNICAL COMMISSION HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES TEST CODE FOR THE DETERMINATION OF AIRBORNE ACOUSTICAL NOISE Part 2-2: Particular requirements for fan heaters FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as IEC Publication(s) ). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC has been prepared by subcommittee 59C: Heating appliances, of IEC technical committee 59: Performance of household and similar electrical appliances. This second edition cancels and replaces the first edition published in 1985 and constitutes a technical revision. The main changes from the previous edition are as follows: provisions with regard to measurement uncertainty and standard deviation for declaration and verification have been included in the scope.

4 IEC:2009 This bilingual version ( ) corresponds to the monolingual English version, published in The text of this standard is based on the following documents: CDV 59C/134/CDV Result on voting 59C/140/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon. This publication has been drafted in accordance with ISO/IEC Directives, Part 2. This part 2-2 is intended to be used in conjunction with IEC , 2nd edition 1997: Household and similar electrical appliances Test code for the determination of airborne acoustical noise Part 1: General requirements. The relevant text of part 1 as amended by this publication establishes the test code for fan heaters. This part 2-2 supplements or modifies the corresponding clauses in IEC :1997. When a particular subclause of part 1 is not mentioned in this part 2-2, that subclause applies as far as reasonable. Where this standard states "addition, "modification or "replacement, the relevant requirement, test specifications or explanatory matter in part 1 shall be adapted accordingly. Subclauses or figures which are additional to those in part 1 are numbered starting from 101. Additional annexes are lettered AA, BB, etc. A list of all the parts in the IEC series, under the general title Household and similar electrical appliances Test code for the determination of airborne acoustical noise, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under " in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.

5 IEC: INTRODUCTION The measuring conditions specified in this part 2-2 provide for sufficient accuracy in determining the noise emitted and comparing the results of measurements taken by different laboratories, whilst simulating as far as possible the practical use of fan heaters. It is recommended to consider the determination of noise levels as part of a comprehensive testing procedure covering many aspects of the properties and performance of fan heaters. NOTE As stated in the introduction to IEC , this test code is concerned with airborne noise only.

6 IEC:2009 HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES TEST CODE FOR THE DETERMINATION OF AIRBORNE ACOUSTICAL NOISE Part 2-2: Particular requirements for fan heaters 1 Scope and object This clause of part 1 is applicable except as follows: 1.1 Scope General Replacement: This standard applies to electric fan heaters, designed for placing on the floor, table or counter, etc., or for wall-mounting. This standard does not apply to electric storage room heaters; room humidifiers; room dehumidifiers; air cleaners; heaters designed exclusively for industrial purposes Types of noise Replacement: ISO , ISO and ISO 3744 can be used for measuring noise emitted by fan heaters Size of the source Replacement: The method specified in ISO 3744 is applicable to noise sources of any size. When applying ISO and ISO , care should be taken that the maximum size of the appliance under test fulfils the requirements specified in Subclause 1.3 of ISO and ISO Object Addition: The frequency range of interest for sound power determination on fan heaters includes at least the octave bands with centre frequencies from 63 Hz to 8000 Hz. NOTE 1 In many cases, the 63 Hz octave band level does not participate significantly to the A-weighted level. NOTE 2 When measuring this 63 Hz octave band, a special attention should be paid to the room effect.

7 IEC: Requirements for the declaration of noise emission values are not within the scope of this standard. NOTE 3 For determining and verifying noise emission values, declared in product specifications, see IEC Measurement uncertainty Replacement: The estimated values of standard deviations of sound power levels, determined according to this standard, are as follows: σ r (repeatability) Standard deviation, db σ R (reproducibility) 0,4 1, Standard deviation for declaration and verification For the purpose of determining and verifying declared noise emission values according to IEC , the following values apply: 2 Normative references Standard deviation, db σ P (production) σ t (total) σ M (reference) 0,3 1,1 1,0 1,6 1,5 This clause of part 1 is applicable.
